Overview

This node performs a regex-based search-and-replace operation on input text. It is useful for scenarios where you need to modify text by replacing parts of it that match a specific regular expression pattern with a replacement string. For example, it can be used to sanitize input data, update formatting, or remove unwanted characters from logs or scraped web content.

Use Case Examples

  1. Replacing all occurrences of a phone number pattern in a text with a placeholder.
  2. Updating date formats in a batch of text data by replacing matched patterns.

Properties

Name Meaning
Input Text The text to process and apply the regex replacement on.
Regex Pattern The regular expression pattern used to find matches in the input text.
Regex Flags Flags for the regular expression, such as 'g' for global replacement, 'i' for case-insensitive matching, or 'm' for multiline mode.
Replacement The text to replace each match of the regex pattern with.

Output

JSON

  • result - The result of the regex replace operation, containing the modified text after replacements.

Dependencies

  • An API key credential for a custom external regex processing service (customJsApi).

Troubleshooting

  • Common issues include invalid regex patterns causing errors, which will be reported in the node's error output.
  • If the API key credential is missing or invalid, the node will fail to authenticate and perform the operation.
  • Ensure the regex flags are correctly set, especially the 'g' flag for global replacement, to replace all matches rather than just the first.
